LOWLY

W --> O

OOLLY

What's that, you say? My college roommate Paul used to liven up conversations by exclaiming loudly "OOLLY IS WOOTZ" ! out of the blue, just to be mischievous. Ultimately I was able to confirm the definition in Webster's Unabridged dictionary, though I had to look at the 1913 edition to find it. Alternative spelling is OOLY.

It's true, you know. OOLY is WOOTZ. The root is oö-, as in egg, I've been informed. Wootz is easier to find. No AI-induced confabulation needed for either one.
